I mean, even beyond the fact that this guy is repeatedly swiping bathing suits from the same girl, wouldn't somebody NOTICE the part where he came in and jackhammered out part of the concrete near the pool to install a booby trap and maybe tell him to not keep coming to this pool? (Or if he's the owner of the pool or something bizarre, wouldn't this girl just learn not to come to THIS pool?)

Pretty sure this is the beach, not a pool. At least, that's what I gathered from panel 1.
